Subject: kABI: protect ife_tlv_meta_decode
Patch-mainline: never, kabi
References: kabi

In networking-stable-18_04_26, commit
cc74eddd0ff325d57373cea99f642b787d7f76f5 (net: sched: ife: handle
malformed tlv length) added one parameter to ife_tlv_meta_decode.
This indeed changed the checksum of this exported function and the kABI
checker now complains.

As this is only an ife internal function, just hide the change from the
kABI checker.
